DOOR-HANGER.

SPECIFICATION formingpart of Letters Patent No. 689,569, dated December24, 1901. Application filed Augnst 17, 1901. Serial No. 72,404.' (Nomodel.)

To all whom it may concern.

Be it known that I, JOHN E. AHLVIN, a citizen of the United States,residing at Joliet, in the county of Will and State of Illinois, haveinvented a new and useful Improvement in Door-Hangers, of which thefollowing is a specification.

My invention relates particularly to slidin gdoor hangers; and myprimary objects are to provide a hanger which cannot be derailed and atrack which can be readily adjusted in case of sagging and'regardless ofthe fact that it may be inclosed between walls.

My invention'is illustrated in the accompanying drawings, in whichFigure 1 represents a track and two doors suspended therefrom, the upperportion only of the doors being shown; Fig. 2, a broken view,in sideelevation,of one-half of thetrack; Fig. 3, a fragmentary view of one ofthe hangers and a door to which it is attached; Fig. 4, a brokensectional view taken as illustrated at line 40f Fig. 3, and Fig. 5 abroken sectional view taken as illustrated at line 5 of Fig. 2.

A A represent the doors; B, hangers connected with the upper portions ofthe doors; 0, a track; D, a central support for the track; E, bracketsfor the ends of the track; E, blocks mounted on inclined ways of thetrack, and E adjusting-rods for the blocks E.

The track preferably comprises a slotted member a of the cross-sectionshown in Fig. 5,said member being provided with upwardlyconvergingsurfaces, which form a ridge for the upper wheels of the door-hangers,and the flange a, which appends from the under surface of the member a,said flange being received at its upper portion by the slot in themember a and secured therein by rivets, as shown. \Vhere the track isreceived between two walls, or rather within a wall which is recessed toreceive the doors and track, the brackets E are supported uponcross-pieces F. Through the ends of the track loosely passvertically-disposed bolts b, which screw into the brackets E. Thebolts 1) are equipped with springs 19, which serve to depress the endsof the track and hold the blocks E in close contact with their guides.The ad usting-rods E pass through the blocks E and are secured thereto,as by nuts 0.

tend from said blocks to near the center of the track and are locatedone in vfront of the web a. and the other in the rear thereof. Near thecenter of their length said rods pass through eyes or staples 0,connected with the web a, and near their inner ends said rods passthrough eyes 0 connected with said web. The rods are threaded at theirinner ends to receive nuts 0 located on opposite sides of eyes 0 Thesupport at D is here shown comprising a cross-piece d and'a bolt d,which passes through the member 0. of the track and through aperforation in the cross-piece d, said nut (1 Each hanger B comprises,preferably, triangular side frames ff, which receive the f supported bythe track member a, a lower grooved wheel f which bears on the loweredge of the web a, cross-bolts f connecting the lower corners ofthe'side frames, hookbolts f depending from the cross-boltf and securedagainst removal therefrom by nuts f and a door-iron f having recessedperforate portions f which receive the bolts f being firmly connectedthereto by nutsf f It readily will be understood from theforegoingdescription that when the ends of the track are inaccessible theynevertheless can be adjusted in height by means of the adjusting-rods,for which purpose it is only necessary to unturn one of the nuts 0 ofeach rod and turn up the other nut thereof, thereby forcing the rodlongitudinally. In this manner the blocks E can be moved either upwardlyor downwardly on their inclined guides to bring the ends of the track ona level with the center of the track, the blocks being always maintainedin contact with their guides by springs. If desired, the center of thetrack may be adjusted also by turning the bolts cl, the nut 01 beingheld against movement by any suitable means.

the position of the track is shown in dotted lines, that the hanger issymmetrically disposed with reference to the track and that it isimpossible with this construction for the door to become derailed. Theadvantage of being able to detach the ends of the track to Said rodsexbring them to a level with the center of the track between them, anupper grooved wheel It will be observed from Fig. 4, wherein bolt beingequipped at its upper end with a track without the necessity of injuringthe wall which receives the sliding door is selfevident. In addition toacting as adjustingrods the rods E assist to a certain extent inpreventing lateral and perpendicular flexure of the track between itscentral point of support and its ends, it being understood that thesprings b may be of sufficient length to hold the blocks E withconsiderable pressure against their guides.

Changes in details of construction within the spirit of my invention maybe made. Hence no limitation is to be understood from the foregoingdetailed description except as shall appear from the appended claims.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a door-track having acentral support, of endsupports for the track comprising inclined guides and tracksupportingblocks movably mounted thereon, springs for yieldingly holding saidblocks in contact with said guides, and adjusting means for said blocks.

2. The combination with a door-track, of

end supports therefor comprising brackets having inclined guides, studson said brackets equipped with springs serving to depress the ends ofthe track, and track-supporting blocks on said guides.

3. The combination of a track comprising a member (it, having awheel-receiving ridge on its upper surface and a web-receiving recess atits lower side and a depending web a set into said recess, and a hangercomprising side frames equipped with interposed wheels bearingrespectively upon said ridge and upon the lower edge of said Web.

4. A door-hanger comprising side frames, track-engaging wheels,cross-bolts connecting the lower portions of the side frames, andhook-bolts depending from said cross-bolts and equipped with nutsserving to prevent disengagement of the hooked portions of the bolt fromsaid cross-bolts.
